Lette/rs Patent N 92,17 7 ,dated July 6, 1869.

f IMPROVEMENT IN LUMB-ER-SLEDS.

The Schedule referred to in these Lettere Patent and making part of the same.

Be it known that I, GEORGE ENGLE, ofP-atch Grove, in the county of Grant, and State of Wisconsin, have invented a new and useful Improvement in Lumber- Sleds; and l dodeclare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation.

Figre 2 is a plan view. y

Figure 3fis a back elevation of the fiont sled.

Figure 4 is a rear elevation' ot' the hack sled.

Letters of like kind denote like parts in eachgure.

This device belongs to the class ot' double sheds intended for use in drawingsaw-logs, timber, and-long hunber of all soi'tsoverrough roads, and is so constructed as to have more licxibility than those in common use.' 1t is found upon trial, in newly-settled and tiinbered countries, where, by necessity, thc roads in use can be iliade only by cutting away the trees, without any attempt at grading the earth, that 'sleds iliade in the usual way, loaded with saw-logs, fence-poles, trees, or other f long lumber, are constantly strained apart and broken' down by the irregularities 'of the surfaceover which the load is drawn, as well as by the frcquciitaud short turns inadenecessary in such rude roads.

This device is designed to have such ilexibilitytof movement in, every direction, and in every part of its construction, as to avoid the rigidity which has proved so injurious to sleds ot' ordinary forni.

A is tliefront sled, and B is the back sled, made in 'the usual forni, with runners G C', rails l) D', and

standards E E E E', exept that in each pair of standards in each sled, one is turned into the ruimer, alittle hack ofthe other, and with roller F, made in the usual manner, to which the tongue is attached. A G and G are the rockers, and

1l is the reach connecting the slcds.

K KK K' are the cross-bars, square at one end and round at the other.

lhe front rocker G traverses on rocker-bar I, by means of a bolt, which passes through the centre ot' said rocker and the frontend ofthe reach H, which is.

tenoned isnto saidrocker, and through the rocker-bar I, which, in tin-n, is pivoted at each end to the square ends ofthe cross-bars K K, by means of two pairs of staples, two of which are in saidv rocker-bar I, and two in said cross-bars K K. l

'lo the cross-bars K K K' K', at their square ends,

the standards E E E E' are tenoned, and their round ends play in staples L L L L' on the under side of the rail l) D', and attached to it in such a manner, that in cach pair `ot' cross-hns to each sled, one end ot' each is rigidly attached to a standard, and one end plays in said staple; and the two bars being side by side, the

rigid end of one and the playing end of the other come together.

The rear rocker G is pivoted to the rear cross-bars K K', iii the saine manner as the iront rocker G to the .rocker-bar I,

ll'ie reach His square where it is tenoned into the cured to their iront ends, hy bolts passingdown through a covering-board, N, and through' said` guides into a cross-brace on the under side ot' said guides. i

On the front end 0i' said reach ll, and near the front rocker G, is a metallic swivel, O, which traverses loosely on said pole, and forms eai's on each side of it.

A i'od, 1, connects it with the front of each runner of the back sled. f c

Behind this swivel is a linclipin, passing .through v.

said reach, which prevents it from drawing out, and

by means of various holes in it, regulates the distance between the slcds. I I In the endsof the rockers are holes for stakes, in the usual way.

I'n operation, and loaded with long lumber of any sort, this double sled has, by means oi' its peculiar construction ot rockers, cross-hais, and reach, a tiexibility, not only of each sled as toward theother, but an independent flexibility, and in addition, an independent l liexibilit-y o't' each runner.'

1t is simple of construction, so thatit can be made hy-,any farmer or woodsinan, Iis cheap, easy of repair, and eiective in its work.

What 1- claim as my invention, and desire'to secure by Letters Patent, is-,

The coustriictiou and arrangement of the cross-bars K K K K', playini/ rl in staples L LL L', so as to set cure an independent flexibility of each runner, as and for the purpose set forth above.

Also, the combinationand arrangement of the rockers G G', rocker-bai' I, cross bars K KK K', reach H, swivel O,.with its rod P and .linchpin, and rails D D', in connection with sleds A and B, when constructed and operating substantially as and for thev purpose described. t a
